Nā hiʻohiʻona huahana
1.He aha ka mea Pc?
PC: polycarbonate, no ka thermoplastic material. He mea akaka keia mea, melemele iki, aole maʻalahi ke hoʻololi i ka waihoʻoluʻu, ʻoʻoleʻa a paʻakikī a ʻoi aku ka nui o ka ikaika o ka hopena, ʻoi aku ma mua o 10 mau manawa ma mua o CR 39, kiʻekiʻe o nā mea thermoplastic. .Paʻa maikaʻi i ka wela, ka pāhawewe wela, ka ea a me ka ozone.Hiki iā ia ke komo i nā kukuna ultraviolet a pau ma lalo o 385nm, e hoʻolilo iā ia i kahi lens palekana.Ma waho aʻe o ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa aila, ka momona a me ka waikawa, ka haʻahaʻa haʻahaʻa o ka wai, kahi kiʻekiʻe kiʻekiʻe o ke kūpaʻa dimensional, ʻo ia ke ʻano o ka mea mālama kaiapuni e hiki ke hoʻohana i nā manawa he nui.ʻO nā hemahema ke koʻikoʻi nui, maʻalahi ka haki, haʻahaʻa haʻahaʻa me nā resins ʻē aʻe, kiʻekiʻe friction coefficient, ʻaʻohe lubrication ponoʻī.
2. ʻO nā hiʻohiʻona nui o ka lens PC:
①māmā ke kaumaha
He 1.2 ka umekaumaha kiko o ka PC, a he 1.32 ka umekaumaha o ka CR-39, he 1.28 ka umekaumaha ko ke aniani, a he 2.61 ko ke aniani.ʻIke loa, ma waena o nā kikoʻī like a me ka nui geometric o ka lens, nā lens PC, ma muli o ka liʻiliʻi liʻiliʻi, e hoʻemi hou i ke kaumaha o nā lens.
②Nīni lahilahi
ʻO 1.591 ka helu hoʻohālikelike PC, ʻo CR-39 (ADC) he 1.499, ʻo 1.553 ka helu hoʻohālikelike waena.ʻOi aku ka kiʻekiʻe o ka huaʻōlelo refractive, ʻoi aku ka lahilahi o nā lens, a ʻo ia hoʻi.Hoʻohālikelike ʻia me nā lens CR39 a me nā lens resin ʻē aʻe, ʻoi aku ka lahilahi o ka ʻaoʻao o ka PC myopia lens.
③Ka palekana maikaʻi
Hiki ke hoʻohana nui ʻia ka lens PC i ka hana ʻana i nā puka makani mokulele, "keaniani" pōkā, nā makamaka a me nā pale.ʻO ka ikaika o ka hopena o ka PC a hiki i ka 87/kg /cm2, ʻoi aku ia ma mua o ka zinc cast a me ka alumini hoʻolei a he 12 mau manawa ma mua o CR-39.Hoʻokomo ʻia nā lens i hana ʻia e PC ma luna o ka lepo sima e hehi ai a ʻaʻole nahā, a ʻo ia wale nō nā lens "ʻaʻole i haki".I kēia manawa, ʻoi aku ka lua o nā lens PC ma ke ʻano o ka palekana.
④ka hoʻopili ʻana i nā kukuna ultraviolet
Ua hōʻoia ka lāʻau lapaʻau hou ʻo ke kukui ultraviolet ke kumu nui o nā cataracts i nā maka.No laila, ʻoi aku ka maʻalahi o nā koi no ka ultraviolet light absorption o nā lens.No nā lens resin optical maʻamau, loaʻa i ka mea pono kekahi ʻāpana o ka hana o ke kukui ultraviolet, akā inā makemake ʻoe e pale pono i ke kukui ultraviolet ma o, pono ʻoe e hoʻohui i kahi nui o nā kukui ultraviolet a hiki i nā lens myopia PC ke 100% poloka ultraviolet māmā.
⑤kūʻai maikaʻi i ka wā
ʻO PC kekahi o nā plastics ʻenekinia me ke kūpaʻa maikaʻi o ka wā.Wahi a ka ʻikepili hoʻokolohua o ka ʻelemakule kūlohelohe waho, ʻaʻole i loli nui ka ikaika tensile, haze a me nā etiolation o PC ma hope o ka waiho ʻana i waho no 3 mau makahiki.
3. He aha ka ʻokoʻa ma waena o HC, HMC a me SHC?
| Paʻa paʻa | ʻO ka uhi AR/Ka uhi nui paʻakikī | Ka uhi ʻana o ka super hydrophobic |
| paʻakikī ka lens uncoated a hoʻonui i ka pale abrasion | hoʻonui i ka transmittance o ka lens a hōʻemi i ka noʻonoʻo ʻana o ka ʻili | hana i ka lens i wai ʻole, antistatic, anti slip a me ka ʻaila |
